The emission spectrum of separated guanine molecules are obtained within a wavelength range of 250–500 nm under the excitation by a low energy electrons beam. Nineteen spectral lines and bands were observed in the spectrum at the 100 eV energy beam. It has been shown that the processes of dissociative excitation of molecules, dissociative excitation with ionization and the primary excitation of the guanine electronic levels induce the guanine radiation spectra. The biophysical implications of the results obtained are discussed.
